Hate this and does seem like it would not be that hard to fix or improve. I have found though that when I first start a game - they will usually eat at the table and there is also not that constantly getting glasses of water or other drinks from the refrigerator or sink. It is only after I have been playing the save for some times that this gets much worse and even with the table set - they will go up several flights of stairs to sit on a bed to eat. They will even sit on their sleeping toddler to eat! The getting drinks increases a lot after a while too. Not sure why it gets worse the longer I play the save but that is what I have noticed.
